Abstract: 134,380. Johnson, J. Y., (Safe-Guard Check-Writer Co.). Nov. 22, 1918. Index type-wheel machines for perforating paper. -A machine for filling-in and safeguarding cheques and the like as described in Specification 134,737, [Class 16, Books &c.], is adapted to print the items of the amount on one line and simultaneously to perforate the cheque across both the amount and the payee's name. The perforations are formed by serrating, abrading, or otherwise opening the fibres of the cheque, and may be produced by a grooved platen which cooperates with the printing- types, these also being in some cases grooved. The types may, if desired, be arranged to apply to the payee's name ink, which may, be of a different colour from that in which the amount is printed. The machine may be arranged to print each of the words that form an item of a line, diagonally to the line and underlapping the preceding word, the arrangement enabling a large number of words to be included in a line; further, the successive diagonal words in a line may be spaced uniformly in order to dispense with the provision of a variable-spacing device. In the machine shown in Figs. 1 and 2, a horizontal type-drum 3 having lines of type 4 for printing words is arranged with the axis at an angle to the line of feed A, B of the cheque, the drum being turned to bring the selected line of type into position above a stationary bar-platen 5 and being then depressed for impression. The shaft 7 of the type-drum is mounted in hubs 8 which are guided by vertical slots 9 in the casing 1, and are formed with arms 10 which are suspended from arms 11 on a shaft 12. The typedrum is depressed for impression by depressing a knob 6, on an arm 15 which is secured to one of the hubs 8. A spiral spring 13 for raising the type-drum is secured to one of the hubs. The type-drum is turned for character selection by means of a knob 21, Fig. 1, which is preferably arranged on the same side as the knob 6 in order to permit of operation of the machine by one hand. The knob 6 may be adapted to turn the type-drum, in which case the knob is geared to the shaft 7 by pinions 22, 23, 24, arranged within the arm 15. The index characters on the knob 21 may, as shown in Fig. 1, be arranged parallel to the line of feed of the cheque, or may be arranged parallel to the axis of the type-drum. The shaft 7 of the type-drum may be mounted eccentrically in hubs journaled in the casing. The axis of the type-drum may be parallel to the line of feed of the cheque, the lines of types being disposed helically and co-operating with a platen of similar shape. Alining for impression.-The type-drum 3 is retained in the set position by a spring blade 20, Fig. 1, adapted to engage notches 26<a>, and is alined by the engagement of notches 26 with a stationary lug 25. Pad inking-arrangements.-The types are inked by a brush 16, mounted in the casing 1, excess ink being removed by a wiping-brush 19 which is secured to a bar 18 carried by arms 17 on the hubo 8 of the type-drum. When the type-drum is depressed for impression, the wiping brush is swung to one side of the printing line. Paper feeding and guiding arrangements; linespacing mechanism.-The cheque or the like is guided at the top edge by adjustable fingers 40 which project through slots 43 in the bed 2 and are secured to a rock-shaft which is frictionally maintained in the adjusted position by a blade spring. The cheque &c. passes between a feedroller 30 and a spring-pressed feed-roller 31, provided with a releasing-lever 38, the feed-roller 30 being provided with the following feeding.mechanism. A ratchet-wheel 33 on the shaft of the roller engages a pawl 34 on a lever 35 which is connected by a link 36 to an arm 37 on the swing- ing carrier 18, described above. When the typedrum rises after effecting impression, the roller 30 is turned to feed the cheque, the feed-movement after each impression being uniform.
